To all whom it may concern:

Be it known that I, JEFFERSON F. Pnmon, a citizen of the United States, residin at Tam a, in the county of Hillsboro and tate of F orida, have invented a new and usefu Electric-Light Stand, of which the followin is a specification.

[his invention relates to electric light The object of the invention is to provide an article of this character that shall be adapted for ready attachment to or detachment from any convenient support, such as arm of a chair, a rolltop or a table, a bench, a book or any other object capable ofsustaining it, and in which the lamp shall be adapted to be turned in any direction or to any angle that may be desired to secure the most advantageous utilization of. the light.

\Vith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists, genorally stated, in an electric li ht stand, em-

lmdyin a base, a lamp stauard rcvolublv assen'ibctl therewith and including a universal joint, a clamping meml'wr uor1i1all housed by the base, and means for holding the clau'iping member assembled with the standard.

The base is' a hollow structure, preferably of spun metal, and the clamping member is a cone-shaped coiled spring, the lower whirl of-which will lie within the plane of the lower edge of the base, whereby to permit the latter to rest upon a table or other support without. danger of wise marring the-same.

if desired, a weight ma y be assembled with the base to cause the latter to sustain the'lamp when moved at ditlerent angles.-

.of which include springs,

The standard a two-part structure, one section of which, as before stated, is assemhlecl with the base and the other section of which is connected in any suitable manner with the lamp socket. The two sections are connected by a universaljoint, the members and means or the same under tension, whereby to to be thoroughly e fiective in desired angle of placing cause thcjoint supporting the lamp at any ad'ustment.

,lhe invention consists further in the varithe back or flatdesk, a

scratching or 0thcr.-'

thereof is omitted.

of a lamp stand constructed in accordance with the present invention. Fig. 2 is a vertical sectional view through the stand. Fig. 3 is a vertical sectional view through a modified form of base that may be employed in lieu of that show-n in 2. Y

l-teferring'to the drawings, and to Figs. 1 and 2 thereof, 1 designates the base, which may be made of any suit-able material, and by preference constructed of spun metal on account of its pcarance; but if preferred the parts may made of cast metal without departing mm .the spirit of the invention.

be lower portion of the base is provided with an outtnrned beaded edge 2, and the head is engaged by the curved edge 3 of an annulus l. the ob cc-t of this latter element being to provide an extended upon which it may rest.

The upper or'dome portion of the base is provided at its center with an. orifice through which projectspthe threaded end of the ower member 4 of he lamp standard, the hipper member 5 of which is connected with the lam socket (3 in any preferred nanner, and as his latter element aswell as the lamp (not shown) and the shade 7 form no part of the present inrcntion, detailed description In order to limit the insertion of the ni'eiiiber 4 of the standard within the base. the former is provided with a stop collar 8 which is preferably integral with the member and bears upon the outer ,surface of the base on the portions surroundingthc orifice. The inner threaded end of the men her 4 is engaged by the inner whirl Not the clamping member," and is held" in position by a tubular collar-'10 that is threadcd onto the inner end oft-he member 4". It is designed that the collarfshall be so seated as to cause the whirl 9 to bear against the hold the lamp at a horizontal lightness and artistic apbearing for? 'illu base to prevent marring'any surface:

The clamping member is herein shown as a cone-shaped coiled s ring, the lower whirl of which will lie within the plane of the under face of the annulus 4,thus to protect the surface upon which the stand will rest. This clamping member is capable of such an extensive adjustment that it will adapt it to grasp any object from the thickness of a book cover to a bench two inches through, wherefore it will be seen that the device may readil be attached to any of the articles referre to at the beginning'of the specification. Moreover, as shown in igi 1, the

clampingmiember will hold the 'stand firmly secured upon the extreme edge of a table or other support, and this feature will-be found of peculiar advantage 'where it is desired to assemble the clamp with a relatively narrow su 0rt.

e form of base shown in-Fig. 1 will support the lamp in vertical or slightly inclined positions'inde endently of the clampingmeinber, but wil not support itwhen the lamp is moved at right angles to the vertical axis of the base, and toadapt the base to this latter purpose, a weight 11 may be assembled with the inner threaded end of the standard member 4", as shown in Fig.

3 and will serve to hold the inner whirl 9 vof 'un housed by these clips is a bloc "lit ed with two orifices l7 and 18 extending 1 the clamping member against disconnection from the said end.

As stated, the two sections 4 and 5 of the standard are-connected by a universal joint, and this joint comprises two yokes, one of flhe other, 13, by the section 5.

which, 12, is carried by the section 4", and In addition to the yoke two clips 14 and 15 are provided,

16 pro- :it' right angles to each other, and in these two orifices are housed two coiled springs l9 and '20. Passing through the yokes, clips,

nd springs, are two screws 21 and 22 that.

are designed to clamp the members of the joint together and also to compress the two" springs 19 and 20, whereby-to cause the ffrictionul contact between the members ofthe joint to be such as positively to hold the lamp it any adjustment required.

As will be obvious by ,.refercnce tollig;

, 1, thelamp may be swung about the stand ard member- 4* as a fix 'axis, and about the two screws 2-1 and" 22 as shifting axes to perinit any. desired degree of angular adjustment that may be required to cuuseftl c light to be directed to the proper point.

' It will be seen'from the foregoing description that'although the improvements herein 'defined. are simple in character they will be thoroughly efiective for the purposes designed and will result iinthe productionof n highly ellicient, durableand convenient form of lamp stand.
